Abstract
C2X communication is made possible efficiently via WLAN by apparatuses and a method for filtering data frames received by a vehicle from a receiver via a WLAN connection, wherein a frame type indicated in a received data frame is used to decide that device to which data in the data frame are transmitted. The C2X communication can be used for recognizing pedestrians. It is also possible to use a plurality of transmission paths and/or UDP.

19. A method for deciding about a further transmission of data frames received by a receiver in a vehicle via a WLAN connection,
wherein a frame type indicated in a received data frame is used to decide about a device to which data in the data frame are transmitted; -
wherein the data are sent to the receiver by a mobile transmission device of a pedestrian; and wherein the data can be used to produce a warning signal in the vehicle. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 37)

30. A method for sending a data frame to a receiver via a WLAN connection, said method comprising the steps of:
-
providing data frames with data from a device processing C2X data with at least one frame type identifier, providing data frames with data from a device processing data other than the C2X data with a different frame type identifier than the frame type identifier used for data originating from the device processing C2X data, before the data frames are sent to the receiver, wherein the receiver is a mobile transmission device of a pedestrian; and wherein the data contain information about a position of a vehicle. - View Dependent Claims (31, 32, 33, 38)

34. A reception device for use in a vehicle, having a decision device for deciding about forwarding, by WLAN, received data frames to a device processing C2X data or to a device processing other data on a basis of at least the frame type of the data frames;
-
wherein the data frames are sent to a receiver by a mobile transmission device of a pedestrian; and wherein the data is configured to be used to produce a warning signal in the vehicle. - View Dependent Claims (35, 39)

36. A transmission device for use in a vehicle for sending data frames to a receiver, said transmission device comprising:
-
a distinguishing device for distinguishing data frames with at least one frame type which originate from a C2X device prior to sending, and for distinguishing data frames with a frame type other than a frame type with which data packets originating from the C2X device are distinguished which originate from a device other than the C2X device; wherein the data frames are configured to be used as a method for pedestrian protection. - View Dependent Claims (40)
